how a cordless impact driver works

Have you ever used a cordless drill to drive screws in and had the screw-head stripped into oblivion? If so, you may want to consider using a cordless impact driver that's created to drive a screw without the hassle of stripping the head of the screw.

A number of manufacturers make these compact, easy-to-use cordless drivers.
